I'm not sure how, but I completely skipped the 9th book in this series. I'll rectify that soon. Tea Time for the Traditionally Built is the 10th book in the No. 1 Ladies' Detective Agency series by Alexander McCall Smith. I have read books from some of the other series by this author and have not liked them at all, but I get a big kick out of these.
from the back of the book:
In this latest installment in the endlessly entertaining series, Precious Ramotswe faces problems both personal and professional.
The first is the potential demise of an old friend, her tiny white van. Recently, it has developed a rather troubling knock, but she dare not consult the estimable Mr. J.L.B. Matekoni for fear he may condemn the vehicle. Meanwhile, her talented assistant Mma Makutsi is plagued by the reappearance of her nemesis, Violet Sephotho, who has taken a job at the Double Comfort Furniture store whose proprietor is none other than Phuti Radiphuti, Mma Makutsi’s fiancé. Finally, the No. 1 Ladies’ Detective Agency has been hired to explain the unexpected losing streak of a local football club, the Kalahari Swoopers. But with Mma Ramotswe on the case, it seems certain that everything will be resolved satisfactorily
